To all whom it may concern:

Be it known that I, THOMAS J. Bu'rnnn a citizen of the United States, residing atjiHarrison, in the county of Hudson and State of I New Jersey, have invented certain new and useful Improvements in Clutches; and I do hereby declare the following to be a full, clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to'lnake and. use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification; y

This invention has reference, general] to improvements in clutches for use mainly in automobiles by means of which the power of the engine may be transmitted to the driving shaft which is geared to an axle of the wheels of the vehicle; and, the present invention relates, more articularly, to a novel clutch which may a e used 'si npl 'as a friction drive, or may be combine with auxiliary devices to provide'a direct' drive between the power-driven shaft: and the axle drivingshaft, and in which the friction-cones are arranged and operate in such a manner that all or only'one of the friction-cones can be thrown infrictional holding engagement with the driving-cone, whereby a smaller or i come.

, My present invention, therefore, has for its. pr ncl 'al objects to rovide a clutch for f automobl es, but which iowever may also be otherwise'used, 1n whicha gradual operative connection 18 made between the powerdriven shaft and the shaft to be driven, and 3 with which may be combined, if desired, and f is preferably used with automobiles, a directa drive or clutch-device between said two shafts, said latterdevice being the-last to be thrown into operation after the friction cones have been set in operation, and being the aged, so that it will be seen, '5 that my novel c utch while it canbe used'as 5 first to be dise a combinedfriction and direct drive, it will also be evident, that the clutch can be used simply in the manner of a friction clutch, and in employing more than one-friction cone, the engaging contact with the driving 'cone can be varied and increased or 'decreased, so that agreater or smaller contacting surface will be the result.

V A further obiect of this invention is to j provide a clutc i-mechanism by which the 5 power of the engine, or other source of mol tive. p'ower, may be steadily and constantly transmitted, and gradually thrown into or out of operation, so as not to cause any injury or reakageby any sudden or undue strain; to avoid the usual discomfoi't to the i person or persons seatedin the vehicle, when 1 starting or stopping the car, as now ordinarily the case an finally, to relieve the shock I or sudden strain which is .occasioned by bringing the parts of the clutch in their operative engagement.

Other objects of this invention not at this j time more particularly mentioned will be clearly understood from the following de- 5 tailed description of this invention. llViththe various objects of my present invention in view, the same consists, primarily, in the novel clutch hereinafter set fort-h; and,'furthermore, this invention consists in the novel arrangements and combij nations of the various devices and parts, as

well as in the details of the construction of i the same, all of which will be hereinafter more fully described and then finally embodied in the clauses of the claims which are apof this specification.

The invention is clearly illustrated in the drawings, in which j main frame of e body of an automobile, F showing in a more general or diagrammatical manner, -one arrangement of my novel clutch-device arran ed between the powerdriven shaft and t e shaft-which is to be l driven.

Fig. 7 is a detail cross-s'ectiori taken on line 77 in said Fig. 2, the fiiction-eone and other-parts of saiddevice being omitted from said view. Fig. 8 is a detail view of the yoke-device emglpyed for the purposes of moving the direct- .the chassis or main frame of the lower bedy 2 are the usual cross-'- ofan automobile, and beams or bars, as shown more particularly in Fi 1 of the drawings.

heclutch-device is illustrated on an enlarged scale in Figs. 2, 4, '6 and 7 of the drawof a driving 40156 3, formed with the chambered part 4, having its'inner annular surface-ta ered or made cone-shaped, substantially in t ie'man-i in said figures of the drawlugs. Connected with the rear Wall 5 of said driving-cone by means of bolts ,6 and nuts 7, said bolts being preferably provided with cylindrical heads 8, is a hub-plate 9, "Said plate has its centrally enlarged part 10 fitted 1nto the centrally disposed open part 11 of said wall 5, and is provided with a receiving 13, as clearly illustrated, boss in any usual manner is adriving shaft 14, which may be providedwith ,-a crank able engine, Suitably secured tonne of the cross-beams or bars 2 of the chassis or frame-work 1, by meansof bolts 16 and nuts 17, is a down wardly extending bracket or support 18 which carries a suitably constructed bearing 19, in whichis \rotatively arranged a shaft 20 which is to be driven from said driving shaft 14*" by means of the clutch which em bodies'the principles of this invention.

Extending into 'eac slot 27 of said ub 26 is a 0st or pin 28, each post. or in radiating om oneof the'corner edges 0 the s uared portion of the shaft 20, substantia y as shown, the s uared portion of said shaft retaining the 'sk'or plate 25 in its slidable operative relation upon said shaft 20. A coiled spring 29 may be arranged upon that part of the hub26, between said pins or posts and the face of the disk or .plate 25, the purpose of which is clearl evident. The disk or late 25 is provide at or 'near its marginal edge with a number of suitably formed openm s.or cutaway parts 30, the number of whic corresponds'to the number I of cylindrical'heads '8 of the bolts 6. Said 0 enings, as will be clearly evident, are fort e pur ose of causing an operative enga ement 0 the direct-drive disk or platewlth the Wall 5 ofcthe drivingcone 3, as clearly- 2 and 3 of the drawings; 'lhe said openings, as will be seen more especially shown in Figs.

'The annular cone- .surface 35 of the friction-conef31 is preferably provided with and is surrounded by an engaging or binding element, as 36, which is usually made of a suitable flexible material, such as leather, rubber, or other fabric, and which is adapted to engage and bind with and upon the inner annular cone-shaped I A coiled spring 35 may be arranged upon that part of the 105 [during the manipulation of the disk or plate surface of the driving made of a suitable flexible leather, rubber, or other fabric, and which driving-cone 3, as clearly i cone 3, substantially as illustrated. In Fig. 7 of the drawings, I have shown the preferred method of securing either of said ins or posts 28 or 34 to the corner-edges of t e squared portion of the shaft- 20. It will be seen, that each in or post is made with a shoulder 37 an a re- I duced and-screw-threaded shank 38 which is screwed into the shaft until the shoulder 37 rests upon the corner edge-portion of the shaft, To prevent the pins or 0st becoming dislodged by vibration, or ot 'erwise, the plns'or posts are provided at or near their ree ends with suitable openings or perforations, as 39, a Wire or other suitable binding stratnd 40 being arranged to connect the severa besufliciently tightened, as at 41, to prevent the unscrewing or loosen-in all of said pins or posts. S idably' disposed upon another part of the squared portion of the shaft ZO is another friction-cone 42 which is provided with a hub 43, and has an annular cone-surface 44 which is with and is surrounded binding element, as 45,

preferablyprovided by-an engaging or which is usually material, such as is adapted to engage and bind-With and upon. the lnner annular. cone-sha ed surface of the 2, 4 and 5 of the drawings.

Upon the, previously mentioned screwthreaded portion 21 of the shaft 20, are usuallyscrew'ed the lock-nuts 46 and 47 and an adjusting nut 48, which latter nut bears against and is for the purpose of regulating the tension ofa coiled spring 49 .which arranged upon said shaft; between the nut- 48 and the end of the hub 43 of the frictioncone 42.

ranged an annular disk or plate 53 provided with a grooved marginal edge-portion intowhich are fitted, substantially as shown in ,the several figures of the drawings, a pair -of-semi-circular members 54, said members being provided with theiperfo'rated endlugs 55 ,ia'nd being secured in place by means pintle ing rods or' stems 63 have their shouldered end-portions 64, which are screw-threaded,

of bolts 56 and nuts 57, as illustrated in Fig. 8 of the drawings. Connectedwith suitable studs-or pins- 58 of each semi-circular member 54 are the end-portions-60 of a yoke 59, said yoke having an upwardly arm or lever 61 which oscillates uponv the 52 hereinabove mentioned.

bodies of said rods extend into and through.

correspondingly located openings -or holes 66 and 67 forme'd'in-the" respective frictioncones 31 and 42, substantially as shown, the cones being capable of moving freely upon said rods. The opposite ends of said rods are formed ith shouldered end-portions 68,

which are screw-threaded, as shown, and are securely screwed in screw-threaded holes 69 in the positive drive-disk or. plate 25. When thus connected, the various devices andparts are operatively connected in the manner clearly represented in Fig. 2 of the drawings'. 61 is pivoted by means. of a pin or bolt 70 the bifurcated; end-portion'72 of. a link 71-,- said link having its "opposite and bifurcated end-portion 73 pivotallyiconnected with a To the upper end of said arm or lever.

crank-arm 74 extending upwardly from" a rock-shaft 75. This rock-shaft has its endportions mounted insuitable bearings 76,

seeFig. 1, and suitably secured upon said a shaft is a lever 77 which is provided-upon its upper free end with a foot-piece 78. Suitably secured upon a portion of the dash 79 of the vehicle is a bracket 80pmvided with a bifurcated part 81 in which ismounted a pintle orpin 82. A bell-crank cnmprisingyan upwardly extending arm 83 and an outwardly extending arm 84 pros vides a suitable trip-device or kick-off for the purposes to be presently described.

- The arm 83 made witha hole 85 to which is secured one end of a coiled spring 86,'said spring having its opposite end attached to E-the dash in any suitablemanner." The arm 84 is made at its forward end-portion in I the form of a toe-piece 87, and its upper marginal edge is made much higher at .88 than at 89, thereby providing a stop-portion 90,

substantially as illustrated. The foot-lever 77 has extending from' its side, nearest the edge-portions 88 and 89 of the arm 84, the distended coils of the spring 86 always tending to producean upward movement of the arm 84, wherebythe upper marginal edge of said arm constantly bears against the stud or lug 91 as will be clearly I understood from an inspection of the several figures of the drawings.

Having thus described the general arrangements and constructions of the various elements which comprise the features of my present invention, forth the manipulation and operations of the I will .now briefly set parts.

Su all t e clutch-devices are in their e aged positions indicated in Fi 20f the graw- ,ings, that is, the positive rive-disk or-plate which rides upon pose, that under normal conditions,

The lever 77 25 is in engagement with "the heads'8 of the bolts 7, and the various friction-cones are in driving frictional engagement with the inner cone-surfaceof the driving-cone 3, and it is desired to throw out of operative engagement the direct-drive. The 0 erator presses upon the foot-piece 7 8 of theever 77, pushing the lever in a direction toward the das The result is that through the'system of levers or arms the disk or plate 25 can be brought into its ino ierative position indicated in Fig. 4, whereby'the positive clutch is cut out. can-be retained in this position by the stud or lug 91 resting against. the

shouldered part 90, as a stop, as shown in. said Fig. 4, in which case the various fr1c-,

tion-cones remain in their operative engagement with the driving-cone. The gagement successively produced by the operator .still further ressing the lever 77 in directions toward iiiie dash, whereb the end of hub of disk or plate 25 is broug tagainst the friction-cone 31 and moves it into the position shown in 5 of the drawings, thereby withdrawing its friction-su rface or member 36 from its frictional engagement or contact with the driving-cone 3, as shown. In this relation, the arts can be readily retained by the operator olding his foot upon the foot-piece 78 of the lever 77. By an additional pressure of the foot upon said foot-piece 78 in the direction toward the dash, the parts are moved into the positions indicated in Fig. 6 of the drawings, the hub of the frictioncone 31 being brought against the frictioncone 42 and moving it forwardly uponthe shaft 20, whereby its friction surface or mem-- ,ber 45 is also withdrawn from its frictional en agenient or contact with the driving cone 3, 1n the manner illustrated in said Fig. 6. I By removing the pressure from the lever '7 7 and, by means of the foot, depressing the arm 84 of the bell-crank, the compressed springs 49, 35 and 29 will act in succession, and will in the following order return the friction-cone 42 and then the friction-cone 31 into their respective frictional engagement with the inner cone-surface of the drivingcone 3, and finally bringing the clutch-disk or plate 25 inits positive holding engagement with he heads 8 of the bolts 6. Thus,

' bv gradually producing the various frictional blIlCllIlgOI'. engaglng relationsof the various parts, the various devices or parts are finally brought together into their positively locked.

relations without any shock in suddenly starting or stopping the vehicle, and without any undue. strain or danger of breakage or damage to the mechanism.

It will also be evident, that the operator will soon learn to use the mechanism for actuating and controlling the 0111 tch-disk 2'5 and the various friction cones in such a manner,

thathe can run'his vehicle with but one of the disen of the various fr ction-cones 1S fiction-cones in actual operation, or with more than'one friction-cone in operation, or with all of the friction-cones and the clutchdisk 2.5 in actual use, as may be desired.

{1 am aware, that various changes may be of the devices an made in the arrangements and combinations their parts, as well-as in the details of theconstruction thereof without departing from the scope of the present invent on, as defined in the appended claims.

Hence I. do not limit my invention to the exact arrangements and combinations of the devices and the. parts thereof, as described 'inthe foregoing specification and as illustrated in the. accompanying drawin s, nor do I confine myself to the exactdetails of the construction ofany of thevsaid parts.
